The solar system installed at this site will provide hot water for the campground showers. Two (2) basic active direct photovoltaic module controlled solar water heating system will be installed at this site. Each system will consist of a 40 square foot solar collector and an 80 gallon solar storage tank. The systems will be mounted adjacent to the shower facility. A tempering valve for each system will control the water temperature to the showers. The tempering valve will serve primarily as a BTU conserver. There will be no back-up water heating source with this solar system.

This site will also incorporate a photovoltaic (PV) system.

SPECIAL CONDITIONS

Storage tank protection

Solar tanks will be installed adjacent to shower facilty. One on one side of the men's shower room, the other on the side of the women's shower room. A weather proof structure for the solar tanks will have to be constructed over each tank.

Roof mount structure

A structure will have to be constructed to mount the solar collectors above the shower stalls. The structure will have to be constructed in a manner meeting the solar water heating system program specification requirements. The structure must also be designed so that the collectors, once attached, will not be obstructed by the bathroom facility roof.

Monitoring equipment

Two BTU meters will be installed at this site. (One each per each seperate solar system system.)
